Full time in New York real estate since 2002
Houses, condos, co-ops, multi-family and mixed-use, commercial and businesses. And when a sale arrives with complications attached — a divorce, an estate, a guardianship, a judge who needs a report — that is the practice I have built since 2004.
Where specialization actually matters
In each of these, the property is only half the problem. The other half is people who don’t agree, a court that has to approve, and a clock nobody controls.
Two people who don’t trust each other have to agree on a price, a broker, a buyer, and a closing date. I work as a neutral — retained by both sides or by agreement of counsel — so the house stops being a bargaining chip and starts being an asset that gets sold properly.
Divorce real estate →I’m on the New York State Office of Court Administration’s Part 36 fiduciary list, eligible for appointment in Kings, Queens, New York, Nassau and Suffolk. I’ve sold occupied properties under court supervision, and I’ll testify when the record needs it.
Guardianship sales →Executors and administrators are usually grieving, often out of state, and personally on the hook if they get it wrong. I handle the house so they can handle everything else — including the parts nobody warned them about, like a sibling living in it.
Estate & probate sales →
Selected from client and attorney testimonials on my public agent profile.
Diallo is one of the most organized, efficient, hard working realtors I’ve encountered in my career in Real Estate Law. We have working together on countless closings, and I have NEVER had a regret recommending him to client, and have continuously marveled at how thoughtful and professional an individual Diallo is.
I strongly recommend the real estate services of Diallo J. Stevens. He sold my house quickly, efficiently, and for $5,000 above asking price. He found my buyer within two or three weeks. He also sold my neighbor’s house just as quickly — and also for more than they were asking.
Diallo took over the renovation and sale of our parents’ properties and carried through even past the final sale and continued making necessary contacts in order to finalize unforeseen administrative details.
The rest of the practice
Divorce, estate and probate, guardianship, seniors, valuations. Those are the areas I’ve trained and specialized in. Underneath them is a full-service general real estate brokerage working nearly every asset class in the New York market — and I take that work happily.
Single-family and condo. Co-op. Two-, three- and four-family. Larger multi-family and mixed-use. Commercial and industrial — warehouses, flex space and office buildings. And businesses: restaurants, franchises and service businesses, with or without the real estate.
How I sell a property →I hold more than one New York broker’s license: my own company, and an associate broker’s license with a firm that belongs to the national REALTOR® association. So the listing route is a decision made for your property, not the one route my company happens to use. Full syndication is available either way, plus marketed exclusives and delayed marketing where privacy and timing are strong considerations.
How your property gets marketed →What a property is worth in this market — current inventory, rates and trend factored in, not just a rear-facing read of closed sales. Plus Retroactive Valuations as of a past date, which most appraisers decline or price out of reach. Fee-based, with no obligation to list.
Fair market & Retroactive Valuations →Hold or sell. Renovate or don’t. Why the listing isn’t moving. What the building should be earning. Paid advice from someone whose compensation doesn’t depend on which way the answer comes out — with no listing attached to it.
Consulting & advisory →Tenant placement and lease-up for owners in Queens, Brooklyn, Nassau and beyond — screened applicants, compliant disclosures, and a lease that holds. I represent owners, not tenants.
Landlord representation →For a small number of owners of two- to twelve-unit buildings: I run the property day to day — tenants, repairs, notices, compliance dates — on a flat monthly fee, and never hold your rent or your deposits. Your vendors invoice you and you pay them directly.
Property operations →Formally trained in buyer representation and working as your fiduciary — obliged to put your interests first — under written agreement, long before the industry required it. Today’s buyer is tomorrow’s seller, and I work accordingly.
Buyer representation →
Standing
Most agents you’ll meet work under a franchise that takes a cut of every deal and sets the rules they operate by. That’s a perfectly good model. It just isn’t built for a case with a judge in it.
I own my brokerage. Nobody upstairs needs the deal to close this quarter, nobody assigns me a script, and when you call the broker, you get the broker — not an assistant, not a team member who joined last spring. In a contested matter that independence is not a marketing line. It’s the reason I can serve as a neutral at all.
I also hold an associate broker’s license with a National Association of REALTORS®-affiliated brokerage, which keeps the corresponding resources available to me and my clients while I preserve our flexibility to do what is best for the specific client.
A first conversation costs nothing and usually clarifies more than people expect — even if the answer turns out to be that you shouldn’t sell yet. I’d like your business, and I’ll tell you plainly whether I’m the right person for it.
